@Ironclad Do you understand the difference between "they did not consider this tradition homosexual" and "there was no homosexuality in their culture"? Secondly, Janet Afary lives in the US and has a whole bingo of modern cultural historians like feminism, gender studies and interest in LGBTQ.
Second, many cultures had a homoerotic connotation in same-sex traditions. For example, Japanese literary tradition even now views ideal friendship as a platonic romance, which you can see in this arc too. But this, firstly, was not their only meaning (even sudo was not always sexual), and secondly, we are talking about a Muslim country of the 19th century. This is far from semi-pagan Persia. Even the Bible has references to this, like the "Our friendship is stronger than the love for women" lines, but you can also find in the same Testament mention of how entire cities were destroyed due to the desire of people to do BL with a couple of bishonens.
I could refer to the fact that my mother's ancestors come from the Middle East, but that is not the point. The question is that Semitic and generally Middle Eastern culture is very different from Western culture, so using such labels for it is as foolish as trying to establish the sexuality of Class S or Homer's characters.
